1WC200平面二次包絡(luò)弧面蝸桿專用機(jī)床設(shè)計(jì)設(shè)計(jì)說明書2010年05月2前言機(jī)械畢業(yè)設(shè)計(jì)是完成大學(xué)全部課程，并進(jìn)行了畢業(yè)實(shí)習(xí)的基礎(chǔ)上進(jìn)行的一個(gè)重要的教學(xué)和學(xué)習(xí)提高環(huán)節(jié)。這次設(shè)計(jì)要求我們能綜合運(yùn)用所學(xué)的基本理論并結(jié)合生產(chǎn)實(shí)際中學(xué)到的實(shí)踐知識(shí)，獨(dú)立地分析和解決工藝問題，初步具備了設(shè)計(jì)一個(gè)中等復(fù)雜程度機(jī)械設(shè)備的能力，也是熟悉和運(yùn)用有關(guān)手冊，圖表等技術(shù)資料及編寫技術(shù)文件的一次實(shí)踐機(jī)會(huì)，為今后從事的工作打下良好的基礎(chǔ)。此次設(shè)計(jì)的課題是WC200平面二次包絡(luò)弧面蝸桿專用機(jī)床設(shè)計(jì)，蝸桿傳動(dòng)是機(jī)械設(shè)備中常用的一種機(jī)械傳動(dòng)。它的主要優(yōu)點(diǎn)是傳動(dòng)比大，結(jié)構(gòu)緊湊，工作平穩(wěn)和噪音小。但是也有發(fā)熱大，效率低，點(diǎn)面易磨損和產(chǎn)生膠合等缺點(diǎn)。目前，這種新型蝸桿傳動(dòng)廣泛應(yīng)用在冶金、礦山、化工、軍工機(jī)械等設(shè)備中。這種新型傳動(dòng)蝸桿的形成原理是齒面以平面為母面，按平面齒齒輪平面包絡(luò)弧面蝸桿傳動(dòng)的共軛嚙合運(yùn)動(dòng)包絡(luò)形成。若進(jìn)行二次包絡(luò)，蝸輪工作齒面就是以該平面包絡(luò)的弧面蝸桿齒面為母面，按新型傳動(dòng)要求的共軛運(yùn)動(dòng)包絡(luò)形成的。通過此次畢業(yè)設(shè)計(jì)使我們熟練地綜合運(yùn)用已學(xué)過的基礎(chǔ)課、技術(shù)基礎(chǔ)課和專業(yè)課認(rèn)識(shí)，分析解決生產(chǎn)實(shí)際問題的能力，同時(shí)學(xué)到處理實(shí)際工程問題的工作方法。鍛煉了我們制定設(shè)計(jì)方案、調(diào)查研究、結(jié)構(gòu)設(shè)計(jì)、實(shí)驗(yàn)分析、理論計(jì)算和計(jì)算機(jī)編程以及繪圖和撰寫技術(shù)文件的能力。此次畢業(yè)設(shè)計(jì)尚有許多不完善之處，敬請(qǐng)指正，以期完善。3PrefaceMechanicaldesigniscompleteauniversitygraduatefullcourse,andhadgraduationpracticeonthebasisofanimportantpartofteachingandlearningimprove.ThedesignrequirementswecanmakecomprehensiveuseofwhattheyhavelearnedthebasictheoryandJieHeproductionShijizhongxuetothepracticalknowledgeandindependentanalysisandproblemsolvingprocess,ChubuwiththedesignofamediumFuzachengduJixieequipmentbuildingisalsofamiliarwithandapplymanual,chartsandothertechnicalinformationandtechnicaldocumentspreparedbyapracticeopportunity,theworkforthefutureandlayagoodfoundation.ThedesignissueisWC200arcplanedoubleenvelopingwormspecificmachine,wormdriveisamechanicaldeviceusedamechanicaltransmission.Itsmainadvantageisthetransmissionratio,compact,smoothandnoise.Butalsohaveafeverandlowefficiency,pointandareaeasytowear,anddisadvantagessuchasproduceglue.Currently,thisnewwormdriveiswidelyusedinmetallurgy,mining,chemical,military,machineryandotherequipment.Thenewdriveprincipleistheformationofwormtoothsurfacetosurfaceasthehomeside,byplaneGear-FlatCurveWormdrive-conjugatekinematicenvelopeformation.Ifthesecondaryenvelopeofwormtoothsurfaceofworkistoarctheplaneenvelopefortheparentwormtoothsurface,accordingtothenewrequirementsoftheconjugatedrivemotionenvelopeformed.Withthisgraduationprojectsothatweskillfullyintegrateduseofthebasiccoursehasbeenlearned,technicalunderstandingofbasiccoursesandspecializedcourses,analyzeandsolvepracticalproblemsofproductioncapacitywhiledealingwithrealengineeringproblemstolearnthemethodsofwork.Exercisetodevelopourdesign,research,structuraldesign,experimentalanalysis,theoreticalcalculationsandcomputerprogrammingandgraphicsandtheabilitytowritetechnicaldocuments.Accesstothedesignofourtrainingmanualsandabilitytochartinformation.Thegraduationtherearemanyimperfections,pleasecorrectme,toperfect.May20104目錄前言.2概述.6一機(jī)械部分.81.1設(shè)計(jì)任務(wù)與要求.81.1.1設(shè)計(jì)任務(wù)：.81.1.2設(shè)計(jì)要求.81.2設(shè)計(jì)依據(jù)和參考方案，設(shè)計(jì)參數(shù)及傳動(dòng)原理圖：.81.2.1生產(chǎn)綱領(lǐng)：批量生產(chǎn)。.81.2.2現(xiàn)有同類型機(jī)床的概況、布局及機(jī)床尺寸參數(shù)的確定：.81.2.3設(shè)計(jì)參數(shù)：.121.2.4傳動(dòng)系統(tǒng)的設(shè)計(jì)：.121.2.5力的輸入輸出過程.131.2.6差動(dòng)箱傳動(dòng)系統(tǒng)設(shè)計(jì).141.2.7機(jī)床的動(dòng)力參數(shù)：.151.2.8幾點(diǎn)說明及本機(jī)床設(shè)計(jì)的特點(diǎn)：.161.2.9機(jī)床的運(yùn)動(dòng)
